NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 693,154, dated February11, 1902. Application filed March 5,1901. Serial No. 49,691. (No model.)

To all whom, it may concern.-

Be it known that we, FRED WILLIAM RIECK and EDWARD WILLIAM EUGE,citizens of the United States, residing at St. Louis, in the State ofMissouri, have invented certain new and useful Improvements inNut-Locks, of which the following is a full and complete specification,such as will enable those skilled in the art to which it appertains tomake and use the same.

This invention relates to nut-locks; and the object thereof is toprovide an improved device of this class which will also serve to coverand shield the nut and the threads of the bolt on which the nut'is.placed, and thus protect both the nut and the threads of the bolt; andwith this and other objects in view the invention consists in a deviceof the class specified constructed as hereinafter described and claimed.

In the drawings forming part of this specification we have shown ourimprovement ap plied to the fish-plates used for connecting therailway-rails of a railway-track, and the invention is fully disclosedin the following specification, of which the accompanying drawings forma part, in which the separate parts of our improvement are designated bythe same reference characters in each of the views, and in which Figure1 is a transverse section of a railway-rail provided with the usualfish-plates and showing our improvement applied thereto; Fig. 2, apartial horizontal section on the line 2 2 of Fig. 1; Fig. 3, an outsideview of a detail of the nut-lock, and Fig. 4 an inside view thereof.

In the drawings forming part of this specification we have shown inFigs. 1 and 2 a railway-rail comprising the usual central vertical web5, the top bearing portion 6, and the base-plate or side flanges 7, andwe have also shown in Figs. 1 and 2 the usual fishplates 9 and 10, whichare used in binding two of the railway-rails together, and in thepractice of our invention we provide a nutlock and nut-protectorcomprisingan inner washer-plate 11 and an outer casing 12, which is openat its inner side, and the sides of the washer-plate 11 and the innerside walls of the casing 12 are beveled, so that said washerplate fitsin said casing, as clearly shown in the drawings.

The outer surface of the washer-plate 11 is corrugated transversely, soas to form transverse depressions 13 and corresponding projecting orthickened portions 14, which are provided alternately with cylindricalmembers 15 in the form of bolts, which are preferably formed integrallytherewith.

The casing 12 is oblong in form, as is also the washer-plate 11, and isprovided with internal rectangular spaces 16, adapted to receive thenuts17 ofthe bolts 18, by which the fish-plates are bound to the rails, saidbolts being also passed through the washerplate 11, as is clearly shown,and the outer surface of the casing 12 is preferably provided withtransverse recesses 19 at points which'correspond with theoutwardly-directed or thickened portions 14 of the washer-plate -11, andthe cylindrical or bolt-shaped members 15 of said washer-plate passoutwardly through the casing 12 at these points, and wedge-shapedkey-pins 20 are passed therethrough, so as to bind the casing 12 to thewasher-plate ll.

The holes or openings in the fish-plates and 'in the plate 11, throughwhich the bolts 18 are passed, are made oblongin form, as shown at 21,so as to permit of expansion and contraction, and the nuts 17 of thebolts 18 are angular in form and designed to fit in the correspondinginternal rectangular spaces 16 in' the casing 12, which prevents saidnuts from turning, and the said nuts and the threaded ends of said boltsare entirely inclosed by the plate 11 and the casing 12, which togethermake up our improved nut-lock and nut-protector.

Our invention is not limited to the exact' form of the parts or members11 and 12 herein shown and described, and changes in and modificationsof the shape and construction of these parts may be made withoutdeparting from the spirit of our invention or sacrificing itsadvantages. cut that this device may be applied to bolts and nutswherever such devices are required, and our invention is not limited tothe appli cation thereof to the fish-plates of railwayrails, as hereinshown and described.

It will also be apparthe edges of the casing lying in the depressions orseats of the Washer-plate, and wedgepins run through the slots of thebolt-like projections of the washer-plate for retaining the casing inposition as and for the purpose described.

In testimony that we claim the foregoing as our invention We have signedour names, in presence of the subscribing witnesses, this 19th day ofFebruary, 1901.
